Yeah the issue is more about
a/ condensation
b/ ventilation.
and getting the balance right.
All I am suggesting is if you do use the reflective air cells under the mattress, more frequent airing is required. Trouble with us is we tend to spend one or two nights in one place more often than not and if you waited in winter for the sun / wind to dry the inside of the canvas/camper before you moved on, there would not be much travel time left in the day!
Post camping trip in the winter/wet, drying out the bedding and canvas are top priority for us now!
We prefer winter camping, less crowds, less bugs, generally no bookings required.
New mattress collected today. Lesson learnt, but will also use some of that Hippo stuff mentioned in other recent posts when storing the camper. What we do now is pop up the camper in the shed for a few days to dry out, even with an oil heater on inside it, that works a treat.
Yep even my double brick cavity wall house here is WA gets cold in winter, mainly because we sleep with at least one window open: it has nothing to do with price of our house/camper! You shoulda seen the condensation in the house we had in Invercargill, NZ, one morning there were stalactites on the inside of the bedroom windows, neighbours' water pipes froze and burst, had to come over to shower at our house. We opened the bath taps waiting for the ice in the pipes to thaw and went down the shops.....
...oops
.... came back home
... rivers down the passage!
All good fun.
